CHARLES C. MORLEY, OF BROOKLYN, AND HENRY O. HINOHOLIFF, OF NEW YORK, N. Y., ASSIGNORS TO SAID CHARLES C. MORLEY.

GLOBE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 391,758, dated October 23, 1888.

Application filed November 14, 1887. Serial No. 255,056. (No model.)

To all whom it may concern:

Be it known that we, CHARLES C. MORLEY and HENRY O. HINOHCLIFF, citizens of the United States, and residents, respectively, of Brooklyn, county of Kings, and State of New York, and of the city, county, and State of New York, have invented certain new and useful Improvementsin Globes for Gas-Burners, of which the following is a specification.

Our invention relates to the novel construction of lamp globes or chimneys, especially to that class of globes belonging to automatic gas igniters.

The invention consists of a lampglobe provided with a corrugation formed upon the glass of the globe and extending from the top to the bottom of the globe, the corrugation being provided with an incision.

In the accompanying drawings, Figure 1 is a view in elevation of such a lamp-globe, and Fig. 2 is a horizontal cross-section of Fig. l at the line 00.

In the drawings, a represents a glass globe havingacorrugation, b, extending from thetop to the bottom of the globe, and an incision, 0, extending along the entire length of the corrugation and being represented in Fig. 1 by a dotted line and in Fig. 2 by an angle on the inner side of the corrugation substantially at right angles to the surface of the glass. It is evident that this incision may be located either upon the inner surface of the corrugation or upon the outer. The incision is made by means of a diamond or a similar glass-cutting instrument; and if it is made upon the inner surface the groove forming the corrugation serves as a guide for the cutting-instrument. If the glass should crack by the influence of heat, it will crack, most probably, (in every instance thus far,) along the cut, while the corrugation will be so much more visible than the crack that the latter will not be noticeable.

lfthe diamond cut is made upon the glass independently of the corrugation, the crack, when it occurs, causes the globe to have'a worthless appearance and makes it objectionable to those who employ the same. Both the corrugation and incision are very much enlarged in the drawings.

We claim as our invention- 1. A lamp-globe provided with a corrugation formed upon the glass of the globe and extending from the top to the bottom of the globe, the corrugation being provided with an incision.

2. A lamp-globe provided with a corrugation and with an incision, the incision being located upon the corrugation.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 11th day of November, 1887.
